n order to pass a title 5 inspection in Massachusetts, the homeowners septic system must be in working order and have certain system components properly installed. The picture above is of an inlet pipe that is missing a tee. The tee stops the waste water from the house from just shooting into the tank and causing a disturbance in the tank. The hardest part about the above tee installation is that the tank is 3′ below grade. Tomorrow we will have to pump the septic tank and install the tee.
